Basic Weld Symbols The basic weld symbols according to IS: 813 – 1961 (reaffirmed 1991) are shown below with sectional representation and symbol in the tabular ..
Shielded Metal-arc Welding (SMAW) is the simplest and used for many joining processes. More than 50% of industrial and maintenance welding currently is performed ..
The process of welding and cutting of metals involve the application of high heat energy to the objects being welded or cut. This high amount of heat energy for welding ..
There are a number of welding processes available; however, their application is dictated by the mechanical properties, type of welded joints, their quality required ..
In Plasma-arc Welding (PAW) is an arc welding process, a concentrated plasma arc is produced and directed towards the weld area. The arc is stable and reaches temperatures ..
Thermit welding is the joining process in which heat required for melting and joining of components is obtained due to the exothermic chemical reaction. When the initiation ..
The ease with which welding of a given material can be done without producing any defect is called Weldability. Weldability can also be defined as the capability ..
Arc Welding Processes In arc welding process, an electric arc between an electrode and a workpiece or between two electrodes is utilized to weld base metals. ..
Defects in welding joints can be classified into two types as external and internal defects. 1. External Defects in welding: External defects of welding include ..
The operator beginning his career in operating arc welding machines must go through and become familiar with these general safety recommendations to avoid accidents ..
There are different joining processes welding, brazing and soldering methods are being used in industries to join, fix metals or alloys. There are different ways ..
The flux-cored arc welding process is shown in image below is similar to Gas Metal-arc Welding, except that the electrode is tubular in shape and is filled with ..
In Submerged-arc Welding (SAW), the weld arc is shielded by a granular flux consisting of lime, silica, manganese oxide, calcium fluoride and other compounds. ..
Welding, soldering and brazing are the metal joining process. Each type of joining process has its own significance. Type of joining process to be applied for joining ..
